Preset metric item reference

Last Updated: Apr 22, 2018

Note:

“Sum” is the sum of values obtained in a statistical period. Take ECS Internet traffic measurement as an example. The unit is KB/min and the statistical period is 5 minutes. Then the returned result is the total traffic in 5 minutes. Interfaces of the new version support query of ECS basic metric data, whereas interfaces of the old version do not. OpenAPI supports the query of metric data from the last 31 days. The Dimensions for each parameter is a JSON string, for example, {"instanceId":"i-23gyb3kkd"}.

ECS metric reference

Basic metrics

No agent is required for obtaining and querying ECS basic metric data.

The project is named “acs_ecs_dashboard”, the sampling period is 60s, and the Period value is 60 or an integer multiple of 60.

The instanceId value for Dimensions is the instanceId of the ECS instance.
